Title: Gas compressor expander
Inventor: HIROSE TATSUYA
IPC: F25B9/06
Filed: 1993-05-14
Abstract: PURPOSE:To prevent a lube oil from invading to a gas compressor expander unit by making a crankcase communicate with a rear space of piston via a communicating tube having an oil filter. CONSTITUTION:A crankcase 21 of a crank drier 4 is connected to communicate with a rear space 22 of a lower piston of a piston 6 via a communicating tube 24 having an oil filter 23. When the piston 6 is driven down, operating gas of the space 22 is passed through the tube 24, fed to the lower crankcase 21. When the piston 6 is driven up, the gas of the crankcase 21 is fed to the space 22 via the tube 24. In this case, lube oil 8 contained in the gas of the crankcase 21 is removed by the filter 23. Thus, a pressure difference between an upper part and a lower part of an oil seal 20 is reduced, the lube oil 8 from the tube 24 is removed by the filter 23 to prevent it from flowing to the space 22 of the piston.

IPC: C23C14/18
Filed: 1984-07-02
Abstract: PURPOSE:To provide a titled heater coil which improves deformation resistance and Al corrosion resistance and extends the service life thereof by forming W which is a blank material into a recrystallized structure. CONSTITUTION:The W which is the blank material for the heater coil for vapor deposition to be used for vapor deposition of the metal back, particularly vapor deposition of Al, on the fluorescent surface of a cathode ray tube panel is subjected to about 1,800 deg.CX70min treatment, etc. in an H2 atm. furnace and is thus made into the recrystallized structure. The residual stress to be generated in the stage of manufacturing the heater coil is thus relieved by which the deformation resistance is improved. In addition, the coarser crystal grains are formed, by which the Al corrosion resistance is improved and the deformation and the decrease in the strand diameter to determine the life of the heater for vapor deposition are lessened. The heater coil for vapor deposition having a long life is thus obtd.
